Key result
Soft catheters, deep intubation, and thin-strut stents are linked to improved PCI success in tortuous arteries.
Why the study?
Percutaneous intervention of tortuous coronary arteries is challenging due to associated complications and requires strategies to improve procedural success.
What are the complications and strategies to improve success during percutaneous coronary intervention in tortuous coronary arteries?
What are the complications and strategies to improve success during percutaneous coronary intervention in tortuous coronary arteries?
Specific procedural strategies, including soft delivery catheters and meticulous vessel preparation, can improve PCI success and reduce complications in tortuous coronary arteries.
May inform technique selection in tortuous PCI; extends Level 5 observations but leaves open randomized validation.
Percutaneous intervention of tortuous coronary arteries can be challenging. We describe four cases that illustrate complications associated with coronary tortuosity (coronary dissection and stent loss) and strategies that can improve procedural success (such as use of soft delivery catheters, deep guide intubation, meticulous vessel preparation, and use of short, thin-strut stents).

Saeed et al. (2008) studied this question. Percutaneous coronary intervention in tortuous arteries risks dissection and stent loss, but success improves with soft catheters, deep guide intubation, and short, thin-strut stents.
